It's not an aimless or endless meme: unusually, it's a meme with a publishable goal. The aim is to come up with limericks for each of the Oxford and Cambridge colleges. Most of the examples so far have been scurrilous in the extreme; I offer this most recent contribution phoned in (well, txted in) by hairyears as an exemplar:
The delicate dons of St Hilda'sThe only rule over and above those dictated by the form is that the limerick must use the name of the college as the primary rhyme (commonly used shortened forms are acceptable, e.g. "Catz" for St Catherine's).
Were shocked by the bill from the builda's
They charged for the water,
The bricks and the mortar,
And labour, replacing the dilda's.
The ultimate aim is to create two full sets of limericks for each university's colleges: one 'clean' (if you could tell it to your mum -- no, not Your Mum -- then it's probably fine) and one, er, not (see e.g. above). We'll collect the best ones (all entries will be subjected to rigorous peer-review through the media of LJ polls and shouting) and hopefully put them together into something on paper that people can keep (think of this as the Viz to Pocketful of Lies' LRB).
For the time being, just post your limericks as comments here or in your own journal with the tag 'oxbridgelimericks'; in time I may be able to find a better home for them, but I don't want to delay the fun because of boring information management issues. Examples have already been sighted in the wild; it's possible that we may be seeing the start of a limerick pandemic (popularly known as 'rhyme flu').
Go forth and versify!
